TestH is an ANSI C library implementing several pseudo-random number generators (PRNGs) for self-similar sequences and several Hurst parameter estimators (also known as the Hurst exponent) described in the literature. It is an on-going research and development project, whose main objective is to provide researchers with the means to estimate the Hurst parameter and to generate sequences with the self-similarity property embedded in the data. It represents an effort to integrate the different methods in a normalized and comprehensive manner in a single software package, which is not found in other tools.
TestH provides a friendly API that allows writing customized programs with ease and few programming skills. The library provides generic methods to instantiate processes (by means of any of the generators or by reading data files), compute statistical information, and submit the processes to estimators of the Hurst parameter while pretty-printing the output.
TestH has been written for researchers and for research purposes. With that in mind, the library can be used in a wide array of research fields.
